Said rotation will feed stem 19 downwardly urging the.

grease in the grease flow to greater speed.'

The volume of chamber 17 can be varied in volume by telescoping theupper'tube 12 into shell. 10 and is retained in any of the extendedpositions by flexible member 26 engaging one of a series of slots 28.

Thus it is apparent that I have provided a grease cup which may .berefilled in a very short time, and which maybe easily and quicklyreplaced with no danger of the .grease escaping or being forced outduring the replacing operation, which is common on the ordinary greasecup and which make When full, the

' the refilling operation very disagreeable and therefore oftenneglected.

I claim- Adevice of the class described comprising a lower shell member,a similar member .slidable therein,.a semi-spherical extension formed onthe bottom of the body of said 1 lower member having a connecting porttherein, and a flat surface thereon, a threaded nipple projecting fromsaid surface, a corresponding inember rotatable on said nipple, thelatter having a port with a distended .mouth, a spring urging 'the lastnamed members into frictional contact witheach other, a pressure plateslidable withinthe shell members means for lowering the .pressure plateand means for lifting the same.

In witness whereof I affix my signature.
